Dpreview posted the full Panasonic GX8 review and writes:

The Panasonic Lumix DMC-GX8 is a impressive mirrorless camera that ticks most of the boxes that many enthusiasts are seeking. Its new 20MP sensor is impressive, Depth from Defocus AF system top-notch, and Dual IS system innovative. The camera’s touchscreen and Wi-Fi features are both well-implemented, and its weather-sealed body is solid.
Still shooters will need to decide whether having to use the electronic shutter to avoid blur is worth its potential trade-offs, while videographers who want to hook up an external mic or HDMI cable may not enjoy losing the flexibility of the camera’s rotating rear screen. It’s for these reasons – especially shutter shock – that we are unable to give the GX8 our highest award.

The new Panasonic Leica 100-400mm lens will finally start to ship next week on March 15 according to BHphoto.

Daniel Cox just returned from Japan where he met with the Panasonic Lumix team and spent ten days photographing Japan’s Winter Wildlife. Most of the work was with the Lumix GX8 and the new Leica 100-400mm zoom. You can see the image gallery here http://archive.naturalexposures.com/proofing/C00003nDou.nKOU0/G0000gFSGHEV7FMk
He also produced a short video on shooting the GX8 in some very wintery conditions:
